C# worked code + support

Dears

I need a c# code to work with bitcoin (send, receive, create wallet, address...) and a support do prepare the computer. Can you help me?

The only library I know is:
http://code.google.com/p/bitcoinsharp/

It hasn't been updated in 6 months but at least the parts I have used (key/address generation) have worked.

It is base off of the java library:
http://code.google.com/p/bitcoinj/

so structure, libraries, design should be similar.

.net developers are a rare breed in Bitcoin.  Hopefully that gets you started.

i know the bitcoinsharp, but it´s not working...

i will try in java...

I  made it work. Some minor changes are needed. I don't warranty that it's correct, but It worked for me.
Best regards,

Can you share the visual studio project?

So what you really need is in fact just JSON-RPC functions in C# to (send, receive, create wallet, address...) to a bitcoind instance ?

If so I might be able to squeeze it in, as I am a C# developer as well.

Should it be a Windows Form or Console application?

Class library would be the best project type to ensure resuability right?
Encapsulate all the JSON logic into a C# library and developers can drop it into any .Net solution (web, console, winform, etc).

If you want to get crazy write up a solution which consists of a class library project, an "example" project, and a unit testing project.

Glad to find at least three other .Net developers.  We are a rare breed in the Bitcoin world.

[Sergio_Demian_Lerner]

When I needed to find a tool to generate some non-standard transactions I tested BitcoinJ and BitcoinSharp.

BitcoinJ requires to install a lot o packages and compiles using maven. I took me more than two hours to make it work.

BitcoinSharp took me less than two minutes.

It's the most simple Bitcoin library.

Yes a Class library, which is just a .dll file to include in your csharp projects, in Visual Studio or SharpDevelop.

[andrehorta]

Anyone can send me the visual studio solution?

[Kris]

If you can wait until Sunday, I can make it for you.

[andrehorta]

Cool! thank you. I´ll wait.

[Vandroiy]

Thanks to everyone who helps making this work!

I know I will need it, and I'd be happy to have a real CLI project instead of BitcoinJ on IKVM.

I have a couple of projects I'd love to add bitcoin functionallity to.  How can I get a hold of this .dll (or the .proj)?  There are probably more .net programmers out there than are willing to admit 

[andrehorta]

I´m still whaiting for the projet in c#.net!

Well the source code is here (including solution & project files)
http://code.google.com/p/bitcoinsharp/

However it hasn't been updated in 6 months.  Up thread someone posted changes they needed to make to get the portion they were using working.

Likely there are other issues but that should get you started.

The optimal solution would be for someone (maybe I am nominating myself) to fork the project and get it current.
